MACHINE FOR MAKING WIRE-BOUN D BARRELS.

Specification of Letters Patent.

Application filed July 30, 1918. Serial No. 247,417.

' To all whom, it may concern:

Be it known that we, EDWARD lVmLIAM tomnsox and Crnnmns JEWELL RoBrNsoN, citizens of the United States, residing in Savannah, Georgia, have invented certain Improvements in Machines for Making Wire-Bound Barrels, of which the following is a specification.

The object of our invention is to simplify and cheapen the construction of the wirebound' barrel-making machine forming the subject of our Letters Patent No. 1,300,025 granted to us on the eighth day of April, 1919, an object which we attain in the manner hereinafter set forth, reference being had to the accompanying drawings, in which- Figure l is a view, partly in side elevation and partly in longitudinal section, of sufiicient of the machine to illustrate our present invention, and

Fig. 2 is a transverse section of the machine on the line 22, Fig. 1, omitting the wire-twisting devices.

So far as regards the means for bilging the staves, the means for imparting back and forth movements of partial rotation to the wire-guiding devices for the purpose of crossing the wires between the successive staves, the means for clamping the bound staves in position as each fresh stave is forced up against the preceding stave, and the means for severing the wires after the complete set of staves has been bound together, the present machine does not differ materially from that of the previous patent, hence it will not be necessary to fully show or describe such elements of the machine. Such parts as are illustrated, however, are numbered the same as corresponding parts in the drawings of our previous patent above referred to.

Our present invention relates to the means employed for wardly the successive staves as they are introduced between the binding wires, and to the relation of the wire-guiding jaws of the twister head to the bilging bridges and to the bilged stave prior to the binding of the latter between the confining wires and to its forward movement against the last of the previously bound staves.

The shafts 2, 4, 5, 48 and 76 are located in substantially the same positions as in the particularly feeding for- 51.5 prior machine except that the shaft 9. is

above the shaft 4, the latter shaft being driven directly from the shaft 2' by means of inter-meshing spur gears 2 and 4*, as shown in Fig. 2. The shaft 3 of the former machine is entirely eliminated, the intermittent driving of. the shaft 5 being effected from the shaft 2 by means similar to those employed in the former machine.

Secured to and rotating with the shaft 4 are a projecting cam 71 and a retracting cam 71 which act upon an anti-friction roller 72 carried by a bar 73 which is slotted as at 71 so as to embrace the shaft 4. The bar 7 3 is connected to an arm 77 on the shaft 76 which also has a series of projecting arms 75, one for each of the dogs 70, whereby the bilged stave is pushed forward against the previously bound staveswhich are held against movement by the clamp 68.

The adjoining faces of the bilgillg bridges 11 and 12 are provided with segmental recesses 87 (Fig. 2) for the reception of the wire-guiding jaws 37 of the twister heads 36, between which jaws the fresh stave passes as it is pushed between the bilging bridges by the dogs 70, the staves being fed transversely along the base 6 of the stave stack by means of a rocking arm 10 slotted, as at 9 for the reception of the fixed fulcrum pin 9, and having rocking movement imparted to it through the medium of a connecting rod 9 from a crank 9 on a short countershaft 8 which is driven from the shaft 4 through the medium of intermeshing bevel wheels 8 and S As the stave is pushed forwardly from between the bilging bridges it passes between the jaws 37 of the twister head, and, as soon as the stave has been dogged forward from between said jaws and the dogs 70 have been withdrawn, the twister head is partially turned so as to twist the wires behind the stave and readjust the jaws for the entrance of the next stave between them.

By reason ofthe formation of the semicircular recesses 37* in the bilging bridges the arms 37 of the twister head can project forwardly beyond the point at which the stave is originally introduced between the bridges in order to have the bilge imparted to it, the semi-circular form of the recesses permitting free movement of the twister head about its axis in order to cross or twist the wires between successive staves, and the now directly Patented Dec. 9, 19159.

contact of the outer faces of the jaws 3? with the inner faces of the recesses rendering unnecessary the employment of the presser fingers 50 and the operating devices therefor shown in our previous Patent No. 1,300,025.

In the present machine the rock shaft 76 is provided with aplurality of arms 7 5, each having a pusher dog 70 so that simple rooking movement of the shaft 76 is all that is necessary to cause simultaneous forward or backward moi'ement of each of the dogs, whereas in our former Patent 1,300,025 and in previous patents based upon the same type of machine the dog carrying arms were mounted so as to swing on ztfiXQCl shaft and an elaborate system of shafts, arms, levers and rods was employed for imparting movement to each of the dogs independently of the others. This multiplicity of parts we have now dispensed with.

It will be evident that our present invention materially simplifies and cheapens the construction of the machine, not only by dispensing with a number of parts of the pre-- vious machine but also by simplifying the mechanism for operating the pusher dogs and controlling the jaws of the twister head.

it also prevents the stave being fed from the hopper from striking against any of the wires by so positioning the jaws 37 in re spect to the feeding position of the stave that t my will embrace it and hold all wires clear of its path.

Vi e therefore claim as our invention:

1. The combination, in the stare feeding mechanism for a wire bound barrel, of a plurality of pusher dogs, a corresponding plurality of arms each integral with its dog, a rock shaft upon which said arms are fixedly mounted, and means for imparting rocking movement to said shaft.

The combination, in a machine for nralring wire-boundbarrels, of stave bilging bridges having, in adjoining faces, semicircular recesses at the rear of the same, a twister head having wire-guiding jaws contained in said recesses, means for introducing successii'e stares between the bilging bridges and said jaws, and means for pushing said stares forwardly from between said jaws.

In testimony whereof we have signed our names to this specification.
